that, and it's missing a space in line 9 as well.

Patch doesn't recognize the hunk in this case, it treats everything
after line 8 of tempname.diff as garbage. The parser either requires
an explicit file name or a patch header (the --- and +++ lines in
unified format) followed by a number of valid hunks; everything else
is treated as "garbage".

It's not so hard to make patch recognize such hunks again, but
then it will more easily misinterpret other text as part of a patch --
it's not so clear that things would improve.

How did you end up with the broken patch? Editing by hand, right?

Thanks,
Andreas
